Monitoring
The ease of deploying new resources
can make the number of servers
grow exponentially. This raises new
issues, and monitoring tools are vital
to system management. First, they
play a basic role in automatic scaling
on a cyclical basis and based on
events. Second, they’re part of the
tools needed to ensure a robust architecture,
as the Netix Chaos Monkey
showed. Finally, they’re important
for detecting security breaches
and forensic investigation, as some
security breaches have shown.
